Description
FIELD OF THE INVENTION

The present invention relates to a PHS mobile phone, more particularly to a method of determining a PHS mobile phone user's exact position by establishing cell station numbers and position information associated with the cell station numbers respectively in a positioning database with extensible functions in the mobile phone so as to enable the user to input new position information in the mobile phone by himself or herself without having to pay any additional fee to PHS service provider while enjoying PHS based position inquiry.

BACKGROUND OF THE INVENTION

A wide variety of consumer electronics products, e.g., GSM (Global System for Mobile Communications) based cellular phones, and PHS (Personal Handy-phone System) mobile phones, etc., are commercially available in an even faster pace in recent years as electronics industry advances. Moreover, they are compact, lightweight, portable, and inexpensive. They are more convenient in use as compared with earlier wireless communication products and Internet access devices. Hence, they are closely associated with our daily life and work.

PHS has made a significant progress in recent years. Also, PHS mobile phones are widely promoted by many telephone companies. As a result, more and more people like to use PHS mobile phones. PHS is a low power communication system. PHS substantially has similar features as GSM. The differences therebetween, i.e., the characteristics of PHS are that the communication signal is transmitted from CS (cell station) to CS as a PHS mobile phone user moves around, the coverage of CS is small and the movement of PHS mobile phone is slow. Thus, PHS is particularly suitable to urban people.

It is a fact that more and more people use such powerful communication tools (i.e., PHS mobile phones) in their daily life. Unfortunately, its powerful features are not fully utilized yet. In comparison with powerful GSM based cellular phones, much less features are employed in PHS mobile phones.

As stated above, the coverage of CS is small. Thus, it is possible of determining a PHS mobile phone user's position more accurate via CSs than that did by a GSM based cellular phone.

PHS based positioning service has not been provided by PHS service providers. It is anticipated that PHS service providers may charge their users for each PHS based positioning service in the future if such positioning service is available. The inventor has been aware of the above trend and for the purpose of meeting market demand; the inventor spends a lot of time to establish a PHS database having a plurality of tables each associated with a corresponding CS number. As such, a location inquiry made by a PHS mobile phone user may result in an exact user position showing on the PHS mobile phone that the user holds. Moreover, the database can be expanded by enabling a user to input new data. Hopefully, the invention can increase competitiveness of one PHS manufacturer among similar products in the market.
